A spaceflight fan’s unofficial render has offered the best look yet at what SpaceX’s Falcon Heavy could look like in the unlikely but not impossible event that NASA decides to launch its uncrewed Orion demonstration mission on commercial rockets.

Oddly enough, the thing that most stands out from artist brickmack’s interpretation of Orion and Falcon Heavy is just how relatively normal the large NASA spacecraft looks atop a SpaceX rocket. The render also serves as a visual reminder of just how little SpaceX would necessarily need to change or re-certify before Falcon Heavy would be able to launch Orion. Aside from the fact that NASA’s Launch Services Program (LSP) is not quite ready to certify the full launch vehicle for NASA missions, very few hurdles appear to stand in the way of Orion launching on a commercial rocket – be it on Falcon Heavy or ULA’s Delta IV Heavy.

In a wholly unexpected announcement made by NASA administrator Jim Bridenstine during a March 13th Congressional hearing, the agency leader revealed that NASA was seriously analyzing the possibility of launching Orion’s uncrewed lunar demonstration mission – known as Exploration Mission 1 (EM-1) – on commercial launch vehicles instead of the agency’s own Space Launch System (SLS) rocket.

The purpose: maintain the missions launch schedule – 2020 – in the face of a relentless barrage of delays facing the SLS rocket, the launch debut of which has effectively been slipped almost three years in the last 18 or so months, with the latest launch date now featuring a median target of November 2021. Some subset of NASA leaders, Congressional supporters, and White House officials have clearly begun to accept that SLS/Orion’s major continued delays are simply unacceptable to both the taxpayer and maintaining appearances, despite the fact that those delays continue to make SLS/Orion an extremely successful example of both corporate welfare and a jobs program.

As it currently stands, a median target of November 2021 for the SLS launch debut guarantees that there is almost certainly no chance of the rocket launching at any point in 2020, even if NASA took the extraordinary step of completely cutting a full-length static fire of the entirely unproven rocket prior to its debut. Known as the “Green Run”, the ~8-minute long static fire test is planned to occur at NASA’s Stennis Space Center on the B2 test stand, which NASA – despite continuous criticism from OIG before and after the decision – has spent more than $350M to refurbish. Stennis B2’s refurbishment was effectively completed just two months ago after the better part of seven years of work.

Put simply, even heroics verging on insanity would be unlikely to get SLS prime contractor Boeing to cut ~12 months off of the rocket’s schedule prevent additional unplanned delays in the 18 or so months between now and an even minutely plausible launch debut target. Admittedly, NASA’s proposed commercial alternative for Orion’s lunar launch debut also offers a range of different but equally concerning risks for the program and mission assurance.

Major challenges remain

On one hand, the task of successfully launching NASA’s Orion spacecraft around the Moon with Delta IV Heavy and Falcon Heavy rockets has a lot going for it, regardless of which rockets launch Orion to LEO or launch the fueled upper stage to boost it around the Moon. In 2014, NASA and ULA successfully launched a partial-fidelity Orion spacecraft to an altitude of 3700 miles (~6000 km), testing some of Orion’s avionics, general spacefaring capabilities, and the craft’s heat shield, although Lockheed Martin has since significantly changed the shield’s design and method of production/installation. Regardless, the EFT-1 test flight means that a solution already more or less exists to mate Orion and its service module (ESM) to a commercial rocket and launch the duo into orbit.

If ULA is unable to essentially produce a Delta IV Heavy from scratch in less than 12-18 months, Falcon Heavy would be next in line to launch Orion/ESM, a use-case that might actually be less absurd than it seems. Thanks to the fact that SpaceX’s payload fairing is actually wider than the large Orion spacecraft (5.2 m (17 ft) vs. 5 m (16.5 ft) in diameter), any major risks of radical aerodynamic problems can be largely retired, although that would still need to be verified with models and/or wind-tunnel testing. The only major change that would need to be certified is ensuring that the Falcon second stage is capable of supporting the Orion/ESM payload, weighing at least ~26 metric tons (~57,000 lb) at launch. The heaviest payloads SpaceX has launched thus far were likely its Iridium NEXT missions, weighing around 9600 kg (21,100 lb).

However, the most difficult aspects of Bridenstine’s proposed alternative are centered around the need for the EM-1 Orion spacecraft to somehow dock with a fueled upper stage meant to be launched separately. Orion in its current EM-1 configuration does not currently have the ability to dock with anything on orbit, a challenge that would require Lockheed Martin and subcontractors to find a way to install the proper hardware and computers and develop software that was – prior to this surprise announcement – only planned to fly on EM-3 (NET 2024). As such, Lockheed Martin – notorious for slow progress, cost overruns, and delays throughout the Orion program – would effectively become the critical path in finishing and installing on-orbit docking capabilities on Orion in less than 12-18 months.

The only alternative would be to have either SpaceX or ULA retrofit some sort of docking mechanism onto one of their upper stages, perhaps less difficult than getting Lockheed Martin to work expediently but still a major challenge for such a short developmental timeframe. Put simply, completing the tasks at hand in the time allotted could easily be beyond the capabilities of old-guard NASA contractors like LockMart and Boeing. Ironically, the upper stage that was designed for EM-1 and is already more or less complete – known as the interim cryogenic propulsion stage (ICPS) – is built by Boeing, the same company that has the most to lose if NASA chooses to make the SLS rocket – which Boeing also builds – functionally redundant with a commercial dual-launch alternative.

Boeing (as part of ULA) effectively completed the first ICPS upper stage for SLS near the end of 2016. It has remained in storage for about two years. (NASA/ULA)

With information currently available, it’s thus reasonable to argue that both launching SLS/Orion in 2020 and launching Orion on Falcon Heavy and/or Delta IV Heavy in 2020 are roughly equal in the level of ambition (insanity?) and increased risk required to attempt either. The question, then, is which risky and extremely difficult challenge – versus doing nothing – is most likely to be in NASA’s best interests?

SpaceX and Elon Musk explain potential reasons for Starship loss

SpaceX and its CEO Elon Musk are starting to shed some light on the potential reasoning for the loss of Starship yesterday, which was lost after a successful launch and catch of the lower-stage booster.

Starship was lost during its ascension, and debris rained down over the Caribbean less than an hour after SpaceX lost all communication with the spacecraft.

A few hours after the launch was over, SpaceX started to shed some light after looking at preliminary data that the rocket left behind.

The company said that a fire developed in the aft section of Starship:

“Following stage separation, the Starship upper stage successfully lit all six Raptor engines and performed its ascent burn to space. Prior to the burn’s completion, telemetry was lost with the vehicle after approximately eight and a half minutes of flight. Initial data indicates a fire developed in the aft section of the ship, leading to a rapid unscheduled disassembly with debris falling into the Atlantic Ocean within the predefined hazard areas.”

Additionally, Musk said that there was some sort of oxygen or fuel leak in the cavity above the ship engine firewall.

The leak was evidently large enough to build more pressure than the vent was able to handle:

Some also seemed to recognize evidence of fires throughout the flight of Starship, which is obviously an anomaly:

There will be more information regarding the loss of Starship in the coming days and weeks, but Musk already believes that a bit of fire suppression and more volume in the cavity above the ship engine firewall could fix the issue.

“Nothing so far suggests pushing next launch past next month,” he said, so Flight 8 could happen sometime in February.

SpaceX completes second catch of lower stage, but loses Starship

SpaceX completed its seventh launch of Starship on Thursday, accomplishing a clean liftoff and catch of the first-stage booster. However, the upper stage was lost after its ascent.

The launch took place just a few minutes after 5 p.m. on the East Coast, as the first attempts at getting Starship in the air for the seventh time were delayed by weather both last week and this week.

Conditions were favorable on Thursday as SpaceX looked to follow up a successful campaign by Blue Origin, Jeff Bezos’s company, earlier today.

SpaceX went into the seventh Starship launch with plans for a catch attempt of the first-stage booster, something it attempted and completed during the fifth test launch last year. It decided to skip a catch attempt with the sixth test flight as conditions were not aligned.

For now, SpaceX is extremely selective as to when it attempts catches.

However, it was successful during this attempt, its second completed catch:

This flight differed from previous launches as SpaceX rolled out several improvements to the rocket and the processes as it featured plans to do a Starlink deployment simulation and had various adjustments to flap placement and avionics.

These plans were disrupted by the fact that SpaceX lost all communications with Starship about ten minutes into the flight, which the aerospace company confirmed was a result of losing the spacecraft sometime during its ascent.

Although the catch was successful, the loss of the actual rocket seemed to be a huge damper on the entire event. SpaceX confirmed several minutes after the loss of communications that the rocket was destroyed and was lost.

It was its first failure since the second Starship launch in November 2023. SpaceX had no answers for why the rocket was destroyed and lost.

We will keep you updated in the coming days.

SpaceX confirms next Starship launch target – Here’s when it will take off

SpaceX has confirmed a new target date for the seventh Starship test launch after weather in Texas delayed the first scheduled date for “three or four days.”

The company is now targeting the launch for Monday, January 13, at 4 p.m. CST or 5 p.m. EST. The launch date is not set in stone as any variety of delays could impact this, but SpaceX hopes to finally take off after a delay that pushed it back from January 10.

What’s new with this Starship launch

With this being the seventh test launch of Starship, there are several things that the company will change and hope to accomplish. All of these launches are done in preparation for eventually taking flight to Mars, something that will happen next year, according to CEO Elon Musk.

First, SpaceX is rolling out a next-generation ship with “significant upgrades.” Forward flaps have been made smaller and are repositioned away from the heat shield, which will “reduce their exposure to reentry heating.”

SpaceX eyes 25 annual Starship launches starting next year

There is also a 25 percent increase in propellant volume, a new fuel feedline system for the Raptor vacuum engines, and a better-than-ever propulsion avionics module that will control the valves and reading sensors.

Avionics, as a whole, underwent a redesign and now have more capability and redundancy for missions as they become more complex.

Starlink test

SpaceX is also planning to deploy 10 Starlink simulators that are similar in size and weight to the next-generation Starlink satellites:

“While in space, Starship will deploy 10 Starlink simulators, similar in size and weight to next-generation Starlink satellites as the first exercise of a satellite deploy mission. The Starlink simulators will be on the same suborbital trajectory as Starship, with splashdown targeted in the Indian Ocean. A relight of a single Raptor engine while in space is also planned.”

Ship return and catch

There will be several experiments that have to do with returning Starship and various catch scenarios and sequences. One of which will see “a significant number of tiles be removed to stress-test vulnerable areas across the vehicle.”

The ship’s reentry profile was also intentionally designed to test the structural limits of the flaps while at the point of maximum dynamic pressure during reentry.

Currently, SpaceX did not detail whether it would attempt another catch during this test launch. These are usually game-time decisions.
